Astronomers have just made an exciting discovery: they have observed for the first time a subpulse drifting and nulling in a pulsar. This is the first time this phenomenon has been seen in a pulsar, and it could help scientists better understand the mysterious objects.

Subpulse drifting is a phenomenon in which short bursts of radio waves are emitted from a pulsar in rapid succession. Nulling is when these short bursts abruptly stop, creating a silence in the radio waves. This new discovery could help astronomers gain a better understanding of how pulsars work and how they interact with their environment.
